The problem is that WPF must be run from a STA thread (one of the inner exceptions above states this). I got this to work by adding the STAThreadAttribute to my Main() method:

using System;

class Program
{
    [STAThread]
    static void Main(string[] args)
    {
        Console.WriteLine("Starting WpfApplication1.exe...");

        var domain = AppDomain.CreateDomain("WpfApplication1Domain");
        try
        {
            domain.ExecuteAssembly("WpfApplication1.exe");
        }
        catch(Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }
        finally
        {
            AppDomain.Unload(domain);
        }

        Console.WriteLine("WpfApplication1.exe exited, exiting now.");
    }
}
